Answer:
Marques De Rubi choose to concentrate on protecting the land instead of extending protection because As a result of his inspection, Rubí recommended that Spain reorganize its frontier defenses along a cordon of fifteen presidios, each about 100 miles apart, that would stretch from the Gulf of California to the mouth of the Guadalupe River in Texas. Above this "real" frontier, which closely approximated the present international boundary between the United States and Mexico, Rubí advised that only San Antonio and Santa Fe be maintained, and he urged the complete abandonment of East Texas. Finally, because of their perfidy and duplicity, Rubí recommended a war of extermination against the Lipan Apaches.
